Why it ranks #1: Its 12-inch dial and weather-resistant metal construction suit outdoor walls, while the listed temperature range extends from -60°F to 140°F.

A 12-inch dial with bold black numbers makes the Taylor in/out thermometer easier to check from a distance on a porch, garage, or garden wall. Its metal housing is described as weather resistant, and the listed temperature range extends from -60°F to 140°F.
